This invention relates to improvements in railway crossings which are built up from tramway or railway rails, and the invention refers more particularly to a means whereby ii the component parts of the crossings are secured to one another and to their respective chairs, soleplates, or tieplates, or any other forms of support.

A, The principal object of our invention is to eliminate all bolts, nuts, keys and the like which are commonly used for securing together the various component parts which go to form a crossing,and substituting metallic bars which may pass through various component members of the crossing and be welded to the said members electrically or by one of the oxy-flame processes or by any other suitable means of welding. Instead of the aforementioned bars passing through the 20 component members of the crossing, they may abut the aforesaid members and be welded thereto as beforementioned. The compo nent rails of a crossing may be secured to the v soleplates, tieplates or chairs by welding as before described, and the rails forming the component parts of the crossing may llkewise be welded together where their heads,

flanges or webs abut. One means of carrying out our invention for building up a crossing of flatbottom rails is, after the component rails have been fabricated'to place the point and splice rails together and secure them by welding to bars of v rectangular or other suitable section, the said bars passing through the webs of the point and splice rails in suitable and predetermined positions, welding up the noses and the webs and the flanges of the crossings is where they abut, then placing the wing rails 40 in position and allowing the aforementioned bars to pass through the webs of the wing rails in lire-determined positions and welding these said bars to the webs of the wing rails. The combination of component parts thus produced may be secured to soleplates, tieplates or chairs by any ordinary means, or may be secured thereto by welding.

It will be seen from the above description that all bolts and rivets have been eliminated from a built-up crossing and their place has been taken by metal bars or rods secured by welding, and these bars not only take the place of bolts and rivets but in themselves act as distance blocks. A crossing constructed from bullhead rails may be built up in exactly the same manner as one constructed of flatbottom rails.

In order that our invention may be clearly visualized and our purposes readily understood, a description will now be given in detail with reference to the accompanying drawings, in which Figure 1 is a plan of a typical railway crossing made from flatbottom rails, but provided with the means offastening described 66 in this invention.

Figure 1 represents a typical railway cross ing built up from flatbottom rails and fabricated by the means of this invention. The rails forming the component parts of the crossing are secured together by means of bars passing through the webs of the rails, these bars being attached to the said webs by the means of fillet welding. The component rails are themselves welded together and t is a cross-section of Figure 1 in turn the whole crossing is welded to soles i plates, the soleplates being attached by any of the usual methods to the sleepers.

In Figures 1, 2, 3, 4, 5, 6 and 7, P is the point rail, SP is the splice rail, and W, V are the wing rails. A, B, C, and D are chair or bearing plates, MB are metallic bars which pass through the webs of the wing rails W, W to the point rail P and the splice rail SP, and MR are metallic rods which are inserted through the webs of the point rail in a manner similar to that in which the metallic bars MB are inserted, the actual section of these metallic rods or metallic bars in no way affecting our invention, their shape or form being such as is best adapted to any particular design or circumstance. The metallic bars MB and the metallic rods MR are in this instance shown attached to the webs of the respective rails by means of fillets of welding deposited electrically or by one of the oxyfiame processes or by any other suitable means of welding. Taken in detail at DD the metallic bar MB secures the splice rail SP to the point rail P, and also acts as a distance block. At C0 the metallic bar MB secures together not only the point rail P and the splice rail SP but also the wing rails W, W, and also acts as a distance block. At EE the metallic rod MR secures together the machined portions of the point rail P and the splice rail SP. At BB the metallic rod MR secures together the point rail P and the wing rails W, W, and also acts as a distance block. At AA the metallic bar MB secures together the wing rails WV, W, and also acts as a distance block. The flanges of the rails, as more particularly indicated in Figures 1, 5 and 7, can be secured together by weldings at FF and the heads of the rails where they meet in the splice can be secured together by welding as indicated at FS. The whole of the crossing may be secured to the chairs as indicated in Figures 1 to 6 by means of fillets of welding FO. These fillets may run longitudinally or transversely or may run both longitudinally and transversely.

In Figures 8, 9, 10 and 11, Figure 8 represents a plan of a bull head crossing built up according to this invention, but the crossing is secured to its chair plates by the means of tapered keys. P is the point rail, and SP is the splice rail, and W, W, are the-wing rails. Metallic bars MB pass through the webs of the point rail P and the splice rail SP and the wing rails W, W, and are secured .by welding as before described to the webs of the said rails. A, B, C, and D are chair plates. Above the chair plate B at the point of the crossing V, metallic'blocks MRB are inserted between the webs of the wing rails and the web of the point rails. These blocks do not pass through the webs of the rail, but they are secured by welding, as before described. The blocks MRB can with advantage in this case be of rectangular section as particularly delineated in Figure 11. The chair plates A, B, C, and D may be provided with jaws J, J, which may be afiixed to the chair plate by welding or by any other suitable means, and keys K, K, may be driven in between the bottom bulb of the rail and the jaw for securely fastening the crossing to the chair plate. The chair plate may be attached to the sleeper by any suitable means of fastening. The means of fabrication of a builtup crossing as shown by this invention gives sufi icient rigidity to the structure as a whole so that the said structure can be secured by means of chair plates as before described.

Another form of attachment which is particularly suited to bull headed rails is indicated in Figures 9 and 12, where CL is a cleat welded to the chair plate B by fillet welding F C. Any number of these cleats may be placed side by side on a chair plate, and can either form the abutment for the rail on the one side of the chair where a key is used on the opposite side, or the cleats may be used on both sides of the chair and Welded, as before described.

Figures 1 to 12 have shown crossings fabricated by this invention secured to chair or hearing plates or chair plates in the form of chairs, but it will be readily understood that the construction admits of the crossings being secured directly or indirectly to steel sleepers; for instance, the crossing delineated in Figure 1 may be welded directly to steel sleepers without the intervention of the chair or hearing plates A, B, C, and D, and further, the whole of a railway turnout comprising switches and crossings and intermediate rails can be fabricated in a like manner.

What we claim and desire to secure by Letters Patent of the United States of Amer- 1ca 1s 1. A railway crossing comprising rails ar ranged side by side in spaced relation and having openings in their webs and metallic bars passed through the said Web openings and welded to the rails, thereby securing them together in their required spaced relation.

2. The method of securing the rails of a railway crossing together, consisting in forming openings in the webs of the rails, arranging the rails in the required spaced relation, passing a metallic bar through the openings of the webs across the rails and welding said bar to the webs of the rails.
